I the accompanying drawing.

Hitherto rolls of paper and the like were protected against damageduring transport by means of several layers of packingpaper wrappedaround such rolls. These layers ofpacking paper were glued together, sothat they formed a protective sheath on the surface of the roll, or,particularly with largerolls, they were held by strips of sheet met-a1,which were secured close to the edges. These known provisions forprotecting paper rolls are, however 'very insuflicient, as they willprotect the circumferential surface of the rolls only against damage,but not the face ends, and least of all the edges, which suffer mostduring transport. The strips of metal laid around therolls at the edgesare of no avail, on the contrary, they-will even be harmful, as theirsharp edges penetrate,

into the paper web, and when they are detached, they will easily tearthe paper. A large number of layers of the paper will be useless,whereby a considerable wastage is caused.

The present invention relates to a protective cover fort paper rolls andthe like, by which thetroubles hereinbefore stated are avoided, as thenew cover will protect the outer face as well as both ends and the edgesof the roll against all damages, and may, be. s1des, be easily appliedand removed, withcuti) giving rise to. any injury to the paper We Thepresent invention is exemplified in Figure 1 a perspective view ofthesame. F g. 2 1s a side view, partly in sectlon. Fig.

3 is a sectional view on an enlarged scale,

and Fig. 4 is a modification in a perspective view. 1 The roll of paperor the like a is wrapped in several layers of a web of paokmg p p I),thewidth of which is greaterthan that of the paper to be covered. Thiscover I) will therefore project at both'ends of the rolls to a more orless great extent. While the packing paper is being wrapped aroundthe-roll,

' and such packingpaper is-coated in known man ner with alayer of anadhesive, so that the.

pressedclose against the ends of the roll. If

it is deemed advisable, circular disks, of pasteboard or paper d may belaid against the ends of the rolls previous to suchfolding down of theends of the wrapper. By such means annular flanges of any desired widthand formed of a pluralityof folds can be produced, and these flanges fwill, afterthe adhesive has hardened and the folds have thus becomefixed, form. very hard and strong protective angular covers 9 at thecorners. These strong, crustlike covers 9 will completel incase theedges of the roll protect them against their being injured. The disks (iwill prevent the adhesive from entering into-the -paper web, when theflanges f are pressed down against its ends. r

If the roll a consists of a web of smooth paper, the wrapper of packingpaper bis made of such a width that when t e projectin'g ends are turneddown and pressed against the ends of the roll, the latter are almostcompletely or completely covered (Fig. t); After the adhesive has dried,the

,roll will. become incased on its face as well as on its ends'within anextremely stiff sheath, which protects the web against injury, and alsoprevents the inner coils from slipping endwise out of the outer coils. A

w1re or cord It may be embodied in the sheath, by means of which thesheath can 'be I Y easily torn open for removing it. I claim:

A paper roll, provided with a cover that extends over the face of theroll andis'provided with a pair ofinwardlyturned' flanges that extendover the ends of the roll, each of said flanges being formed ofaplurality. of

folds, and with a hardening adhesive carried by the cover, and adaptedto stiffen the flanges andfix the folds thereofQ 7 In testimony whereofI hereto aflix my signature'in the presence of two witnesses.
